My 6 yr old sony vaio keyboard that came with my sony vaio space bar and escape button is not working. My wife frequently eats her meals over this thing. I occasionally have to shake all the crumbs out of it. is this thing salvageable? a few weeks ago, the spacebar was hard to push, but then it got easier, after I shook the beejezus out of it. now when you push it, nothing. same thing with the escape button. I see that there are plenty of screws on the back of it and I'm about to take it apart. I'm using a ten year old sony vaio keyboard in it's place. As you can tell, I like to hoard things..
